DESCRIPTION
The M74HC85 is an high speed CMOS 4-BIT
MAGNITUDE COMPARATOR fabricated with
silicon gate C²MOS technology.
This comparator compares two 4-bit words and
provides an high voltage level on one of the A>B
out, A=B out and A<B out outputs. The comparing

bit number is easily expanded by cascading
several devices as shown in the typical
application.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
